XCP-R3670 Crystalline Polyester Polyol – Direct Alternative to DYNACOLL® 7360

2026 08/01

Today we mainly introduce XCP-R3670, which is a medium molecular weight crystalline polyester-polyol for reactive hotmelts. It has a glass transition temperature (Tg) of 55°C and the open time is 30 seconds, which can be used as a full drop-in replacement for Evonik DYNACOLL® 7360.

Key Advantages:
1.Low melt viscosity, good processability on standard hot melt equipment
2.Fast crystallization, short setting time and high green strength
3.Balanced open time & setting performance
4.Excellent compatibility with MDI; good adhesion on wood, textile, plastics & automotive substrates
